RESUMO: A produção de concreto em usinas dosadoras está em crescimento e, com isso, há também o aumento de resíduos inerentes do processo produtivo. O objetivo deste artigo, é verificar o panorama das pesquisas relacionadas com a lama residual de concreto, com ênfase na sua reciclagem em unidades de alvenaria. Para tanto, foi realizado o mapeamento sistêmico com a finalidade de encontrar as principais publicações e estudos referentes a vertente desejada, através da base de dados Periódicos CAPES, sendo as buscas pertencentes a dois tópicos principais: utilização de resíduos em alvenarias de concreto e estudos relacionados com a lama residual de concreto. Em linhas gerais, pode-se observar que há uma grande variedade de resíduos aplicados em alvenarias, sendo o mais estudado a utilização de cinzas volantes e resíduos de construção e demolição. Em contrapartida, ainda são poucos os estudos que utilizam a lama residual em produtos de concreto, sobretudo para produção de alvenarias. Nesse contexto, entende-se que não há um consenso quanto à melhor utilização da lama residual de concreto, ressaltando a necessidade de pesquisas que corroborem ou contradigam os resultados obtidos. Por fim, esse trabalho aponta um resíduo ainda pouco estudado, mas com possíveis aplicações em novas pesquisas. Suas características como, por exemplo, presença de SiO2 e CaO apontam um potencial para uso como aglomerante, o que pode gerar uma redução no consumo de cimento.
 
 ABSTRACT: The production of concrete in dosing plants is growing and, with this, there is also an increase of inherent residues of the production process. The objective of this paper is to verify the panorama of the research related to residual sludge of concrete with emphasis on its recycling in masonry units. In order to do so, the systemic mapping was performed with the purpose of finding main publications and studies referring to the desired slope, through the CAPES Periodic database, and the searches belong to two main topics: the use of residues in concrete masonry and studies related to concrete sludge waste. In general, it can be observed that there is a great variety of residues applied in masonry, being the most studied the use of fly ash and construction and demolition residues. On the other hand, there are still few studies that use residual sludge in concrete products, mainly for the production of masonry. In this context, it is understood that there is no consensus regarding the best use of concrete sludge waste, emphasizing the need for research to corroborate or contradict the results obtained. Finally, this work points to a residue that has not yet been studied, but with possible applications in new research. Its characteristics such as the presence of SiO2 and CaO indicate a potential for use as a binder, which can lead to a reduction in the consumption of cement.

Ideas of nationalisms as masculine projects dominate literary texts by African male writers. The texts mirror the ways in which gender differentiation sanctions nationalist discourses and in turn how nationalist discourses reinforce gender hierarchies. This article draws on theoretical insights from the work of Anne McClintock and Elleke Boehmer to analyse two plays: Zintgraff and the Battle of Mankon by Bole Butake and Gilbert Doho and Hard Choice by Sunnie Ododo. The article argues that women are represented in these two plays as having an ambiguous relationship to nationalism. On the one hand, women are seen actively changing the face of politics in their societies, but on the other hand, the means by which they do so reduces them to stereotypes of their gender.

This chapter presents a reading of Plato’s Euthyphro, Apology, and Crito. These dialogues, in which Plato depicts the weeks leading up to Socrates’s last day, are replete with various philosophical explorations. Among those explorations is the question of how to live our lives. On the one hand, Socrates is clear and straightforward. We should live the examined life—making logoi and examining ourselves and others in order to determine whether we are as wise as we think we are, and we should live the virtuous life. This is how Socrates lives his life. On the other hand, the examined life undercuts, or at least should undercut, the confidence with which he seeks to live the virtuous life. It may help bring some stability to the general principles by which he lives his life, but it can do so only defeasibly and without certainty.

We describe and analyze the previously undocumented verbal agreement system of Kutchi (Indo-Aryan). We argue that Kutchi instantiates a novel type of split ergativity. First, it exhibits an aspect split in that agreement in non-perfective clauses behaves on a par with agreement in intransitive perfective clauses, in stark contrast to transitive perfective clauses. A striking property of Kutchi is that these asymmetries manifest themselves in the richness of agreement. In the former configurations, the verb agrees with the subject for person, number and gender. In the latter, on the other hand, agreement is systematically defective and reliable fails to cross-references certain φ-features. In addition to this aspect split, Kutchi displays a person split: While the verb normally agrees with the subject, it surprisingly fails to do so in transitive perfective clauses with a 1st person subject. Instead, it is the object that triggers agreement in these configurations, likewise in a defective manner. We will argue that these agreement asymmetries are syntactic in nature rather than morphological. Our analysis builds on, and extends, previous work by Laka (2006) and Coon (2010).

AbstractAn increasing number of studies are being devoted to the investigation of what aspects of grammar, and of events, expressed in speech are coordinated with gesture. However, previous studies have focused on gesture use in relation to either transitivity or event properties, without considering how these factors interact. In this study, we consider how gesture use relates to transitivity when the type of event in the causativeinchoative alternation is considered, and also how gesture use relates to properties of the events when the type of transitivity is considered. We found various relations both between gesture use and transitivity on the one hand, and between gesture use and certain properties of events on the other hand. Whereas some of the results contrast with the findings in previous studies about the relation between gesture and transitivity, other results obtained actually reinforce and complement some previous findings. The results concerning event properties and gesture also add to previous studies about which properties of certain motor-spatial events relate to gesture and how they do so. The study thus provides a more nuanced understanding of the relation between gesture and language.

Concrete is the most widely used building material and due to its use, water tightness is one of the factors essential for many constructions. Materials applied on concrete surface as secondary protection can have various forms. One of the material group with waterproofing ability, are materials on so called "crystalline technology base". As this material is cement-based its wide world production brings significant effect on environment. To bring on building materials market new materials should be considered its environmental friendlier production. One of the ways for this group of materials with crystalline abilities is replacing cement by other substituent, at best by secondary raw material. This would bring double advantage, lowering usage of cement and on the other hand use of already produced secondary raw material. This article deals with new developed materials based on "crystalline technology" with cement partly replaced by fly-ash substituent. At this article are presented results of new developed screed and coating modifications and its effectiveness on concrete waterproofing.

We discuss the consequences of the possibility that Vassiliev invariants do not detect knot invertibility as well as the fact that quantum Lie group invariants are known not to do so. On the other hand, finite group invariants, such as the set of homomorphisms from the knot group to M11, can detect knot invertibility. For many natural classes of knot invariants, including Vassiliev invariants and quantum Lie group invariants, we can conclude that the invariants either distinguish all oriented knots, or there exist prime, unoriented knots which they do not distinguish.

This article aimed to analyze the stereotypes attributed to "egalitarian men", understood here as men who support gender equality in relation to domestic and family responsibilities as well as inclusion in the workforce. To do so, two studies were carried out. The first study investigated the attribution of stereotypes to egalitarian men through a single open question. A total of 250 university students participated in this study, of which 51.1% were male, and their average age was 21.5 years (SD = 4.39). The second study analyzed the attribution of stereotypes to egalitarian or traditional men and women in a work context considered masculine. Participants included 221 university students with a mean age of 21.9 years (SD = 4.19), the majority (54.3%) being male. Taken together, the results of the two studies indicate that the egalitarian man is perceived as fragile and possibly homosexual. On the other hand, he is also seen as being more competent than traditional men.

ResumoA compreensão de quilombo como território de resistência e preservação da cultura de base africana perpassa os discursos de pesquisadores diversos, como Almeida, O’Dwyer e Arruti, inserindo-se nas análises deste último as ressemantizações sofridas pelo termo e os determinantes históricos que as trouxeram à luz. A ressemantização, ainda segundo Arruti, que interpreta quilombo como território de resistência, vai compor as bandeiras do Movimento Negro Unificado (MNU). Por outro lado, o entendimento de currículo como relação de poder e como instrumento/estratégia capaz de interferir na formação do outro revela o quanto este instituto pedagógico é capaz de inserir/excluir, empoderar/fragilizar, desvelar/camuflar. É neste cenário de entendimentos que se insereeste artigo, objetivando pensar/propor saberes capazes de fomentar a Educação Escolar Quilombola nosterritórios dos remanescentes quilombos e nas unidades de ensino que atendem a estudantes originários/as daquelas comunidades. Para tanto, construímos diálogos com as legislações (vigentes) e com teóricos que abordam a temática. Palavras-chave: quilombo; currículo; educação escolar quilombola. Reflections on quilombola school education: elements for teaching practice AbstractThe understanding of a quilombo as a resistance territory and african culture preservation territory permeates the words of several researchers, such as Almeida, O’Dwyer and Arruti, being inserted in the last author’s analysis the changes in meaning suffered by the expression and the historical determinants which brought those to light. – It’s precisely the change in meaning, still according to Arruti, who interprets a quilombo as a space/time of resistance that will compose the flags of the United Black Movement (UBM). On the other hand, the understanding of curriculum as a power relation and as a tool/strategy capable of interfering in the formation of other emphasizes how much this pedagogic institute is able to insert/exclude, empower/weaken, revealing/hiding. It is in such a scenario of thoughts and understandings that this article is inserted, aiming to think/propose knowledges capable of promoting Quilombola School Education in the territories of the remaining quilombos and at the educational units that assist students originated/from that community. To do so, we have established dialogues with legislations (in effect) and also with theorists who do research on the topic.Keywords: quilombo; curriculum; quilombola school education.

In the leather industry, a production process that is the subject of many different disciplines is dominant. Many studies on these branches of science have examined the sector in detail in terms of production. On the other hand, studies dealing with the sector in terms of business administration department and sub-disciplines are not common. In this study, academic publications examining the relationship between the leather industry and the business administration department are the subjects. 98 scientific studies obtained after the search in the Web of Science database were examined in terms of the form of publication, the year of publication, the country where the publication was made and the sub-disciplines of the business department.

This paper  describes the importance of the raw materials Inventory supervision for production process. The concepts described in this paper was studied using the descriptive theoretical analysis. It is concluded that (1)  Raw Materials Inventory control is highly needed by both small and big companies to take care of the production process stabilization; (2) The production process will find problems when there is no good control of the Inventory. This causes anstable production process effecting finnace of the companies. The long period of materials inventory causes campany loss. On the other hand, small amount of inventory will also cause the production processes stop. Such situation will also influence marketting and the supply to the consumers; (3) Unstable producation process will cause unstable product supply in the market, and (4) To ensure that the consumers’ needs are continuously completed, control of the raw materials inventory needs to be done and maintained.
